Hi everyone, i was wondering, what do you use to cut foam? I know some people buy special foam cutters and stuff but its not really much of an option for me, i'm on a small budget :/
Anybody used exacto knives? if so where do you buy them?

Thank you all for the help

I use razor blades.  Very cheap and easy to replace.  They get dull pretty fast.

You can also use a sharp kitchen knife. Foam does dull pretty much anything you use pretty fast. With a knife if you have a sharpener you can keep it sharpened. Razor blades are good like anglered4kids mentioned and you can get a whole box of them for pretty cheap. Check your hobby store. Look for the ones that are exposed on just one side that have the other side covered in a bit of metal that acts kind of like a handle of sorts.

I get my razor blades at Lowes or Home Depot. Pretty cheap for a box of 100.

ok thanks you guys, i had seen in the project puppet tutorial videos that razor blades seemed to work pretty well, so i'll look into that. and they're at home depot? this just gets easier and easier
